Abstract

A recording apparatus for performing recording on a recording medium (301, 302) includes a mounting unit, a discriminating unit (135, 136), a recording unit (130), and a control unit. The mounting unit detachably mounts an ink sheet (132a, b), the discriminating unit discriminates a kind of ink sheet mounted in the mounting unit. The recording unit performs recording on the recording medium and has a plurality of recording elements. The control control unit performs drive control of the recording elements on the basis of a discrimination result of the discriminating unit.
